Memorial Day weekend is the unofficial start of summer in Chicago, which also makes it the unofficial start of summer violence. Why it matters: The holiday weekend is used as a litmus test to gauge whether preventative programs and police practices are working to curb gun violence.

Asked whether he would be open to any deal allowing the Chicago Bears to break their Soldier Field lease, Mayor Brandon Johnson said “it hasn’t come up.”

Several Chicago festivals, events, and concerts are happening this Memorial Day weekend to kick off the unofficial start to summer, but the warmer months also typically bring a rise in violent crime.
